1.Introduction
The 6 in 1 digital multi-tester has been designed to combine the
functions of Sound Level Meter, Light Meter, Humidity Meter,
Temperature Meter Non-contact AC Voltage Test Meter and Digital
Multimeter.
It is an ideal multi-function Instrument with scores of practical
applications for professional and home use.
The Sound Level function can be used to measure noise in factories,
schools, offices, airports, home, etc., checking acoustics of studios,
auditoriums and hi-fi installations.
The Light function is used to measure illuminance in the field. It is
fully cosine corrected for the angular incidence of light. The light
sensitive component used in the meter is a very Stable, long life
silicon diode.
The Temperature is for use a semiconductor sensor and K type
thermocouple. This operations manual contains general information
and specification.
The digital Multimeter performs AC/DC Voltage, AC/DC Current,
Resistance measurement and Audible Continuity, Diode, Temperature
test.

6.Operating Instruction
6-1 Measuring Sound Level
•Set the function switch to the green “dB” position.
•Remove the meter and face the microphone to sound source in a
horizontal position.
•The C-weighting curve is nearly uniform over the frequency range
from 30 to 10,000Hz, thus giving an indication of overall Sound
level.
•The Fast response is suitable to measure shout bursts and peak
values from sound source.
•The sound level will be displayed.
Note: Strong wind (over 10m/sec.) striking the microphone can cause
misreading for measurement in windy locations, a windscreen
should be used in front of microphone.
6-2 Measuring Humidity
•Humidity Measurement for indoor.
•Set the function switch to the ON position.
•Remove the meter place to the room.
•Read the %RH in the display for about two hours.
6-3 Measuring Light
•Set the function switch to the green “Lux” scale and set the range
to desired (“Lux” or “x10 Lux”) range.
•Remove the meter and face the photo detector to light source in a
horizontal position.
•Read the illuminance nominal from the LCD display.
•Over-range: If the instrument only display one “1” in the M.S.D. the
input signal is too strong, and a higher range should be selected.
•When the measurement is completed. Replace the photo detector
from the light source.
•Spectral sensitivity characteristic: To the detector, the applied photo
diode with filters makes the spectral sensitivity characteristic almost
meet C.I.E. (International Commission on Illumination) photopia
curve V (λ) as the following chart described.

7.Maintenance
Battery and Fuse Replacement
If the sign “
” appears on the LCD display, it indicates that the
battery should be replaced. Remove screws on the back cover and
open the case. Replace the exhausted battery with new batteries.
(1 x 9V battery NEDA 1604, 6F22 or equivalent)
Fuse rarely need replacement and blow almost always as a result of
the operator’s error. Open the case as and replace the blown fuse
with ratings specified.
Warning:
Before attempting to open the case, be sure that test leads have been
disconnected from measurement circuit to avoid electric shock hazard.
Replace fuse only with specified ratings:
Fuse1: F10A / 600V fast blow.
Fuse2: F500mA / 660V fast blow.
